Measles - Fact Sheet for Parents

Diseases and the Vaccines that Prevent Them

Español: Sarampión

What is measles?

Measles is a serious respiratory disease caused by a virus. It spreads easily through coughing and sneezing. In rare cases, it can be deadly. The measles, mumps, rubella (MMR) vaccine protects against measles.

What are the symptoms of measles?

  • Measles starts with a fever, which can get very high.
  • Soon after, it causes a cough, runny nose, and red eyes.
  • Then a rash of tiny, red spots breaks out. It starts at the head and spreads to the rest of the body.
  • The rash can last for a week, and coughing can last for 10 days.
  • Some children who get measles also get diarrhea or an ear infection.

How serious is measles?

Measles can be dangerous, especially for babies and young children. In the United States in 2011, 42% of children under 5 years old who had measles had to be treated in the hospital.
For some children, measles can lead to pneumonia, a serious lung infection. It can also cause lifelong brain damage, deafness, and even death. One to three out of 1,000 children in the U.S. who get measles will die from the disease, even with the best care. About 150,000 to 175,000 people die from measles each year around the world—mostly in places where children do not get the measles vaccine.

How does measles spread?

Measles spreads when an infected person breathes, coughs, or sneezes.
It is very contagious. You can catch measles just by being in a room where a person with measles has been, even after that person is gone. And you can catch measles from an infected person even before they have measles rash.

What is the MMR vaccine?

The MMR vaccine is a shot that combines vaccines for three diseases—measles, mumps, and rubella. The vaccine protects children by preparing their bodies to fight the measles virus. Almost all children (95 children out of 100) who get two doses of MMR vaccine will be protected from measles.

Why should my child get the MMR vaccine?

Getting your child the MMR vaccine protects him or her against measles. It also protects other people who can’t get the vaccine. For example, babies under 1 year old are too young to get the vaccine, but they can still get sick with measles. Also, children with cancer or other serious problems with their immune systems cannot be vaccinated. A high level of vaccination in the community helps protect these children.

When should my child get the MMR vaccine?

Children should get two doses of the MMR vaccine for best protection:
  • The first dose at 12 through 15 months, and
  • The second dose at 4 through 6 years of age.
Children often get MMR vaccine at the same time as other vaccines. This is safe, even for young children.
During an outbreak, health officials may recommend the MMR vaccine be given to infants younger than 12 through 15 months of age, sometimes even to children as young as 6 months of age.
Additionally, measles is still common in many countries, including Europe, Asia, the Pacific, and Africa.  Worldwide, about 20 million people get measles each year.  So,  the risk of measles may be very high for unvaccinated U.S. residents who travel abroad.  Two doses of MMR vaccine are recommended for all international travelers 12 months or older. Infants 6 through 11 months of age should get one dose before traveling.

Is the MMR vaccine safe?

The MMR vaccine is very safe, and it is effective at preventing measles (as well as mumps and rubella). Vaccines, like any medicine, can have side effects. Most children who get the MMR vaccine have no side effects. Those that do occur are typically very mild, such as a fever or rash.

What can I do to protect my child from measles? Vaccinate your child on time. Talk with your child’s doctor if you have questions. Keep a record of your child’s vaccinations to make sure your child is up-to-date.If my child does not get the MMR vaccine, will he get measles?

Almost everyone who has not had MMR vaccine will get measles if they are exposed to the measles virus.
Before the measles vaccination program started in 1963, about 3 to 4 million people got measles each year in the United States. Also, about 48,000 people were hospitalized, 1,000 suffered brain damage or became deaf, and 450 died because of measles each year.
Thanks to the MMR vaccine, measles no longer circulates year round in the United States. But, measles is still common in other parts of the world, including Europe, Asia, the Pacific, and Africa. Unvaccinated people can get measles when they are in other countries and bring it into the United States. They can infect other people, which can cause outbreaks in their communities.
Today, only about 60 people in the United States are reported to have measles each year. But this number can go up when people don’t get the vaccine and are exposed to measles. In the late 1980s, measles cases went way up—and so did measles deaths—due to large numbers of unvaccinated children in some communities.
In 2011, the number of people reported to have measles in the United States was higher than usual. There were 222 people who were reported to have the disease. That’s more than any year since 1996. Measles sent 31% of these people to the hospital. People who had measles spread the disease to others. This caused 17 different measles outbreaks in 2011.

Where do measles cases in the United States come from?

Most measles comes into the United States by U.S. travelers who recently traveled internationally and foreign visitors.
Some people in the United Stateschoose not to get their children the MMR vaccine. These children are at higher risk for getting measles. And they can spread the disease to others in their communities, including to babies who are too young to get the vaccine and others who cannot get vaccinated because of certain health conditions.

Is the MMR vaccine linked with autism?

No, many large and reliable studies of MMR vaccine have been done in the U.S. and other countries. None has found a link between autism and the MMR vaccine.
There are a couple of reasons why people believe autism is linked to vaccination. The first is because sometimes signs of autism do not appear until around the age the MMR vaccine is given. If a child is diagnosed shortly after getting vaccinated, this may seem like the vaccine caused autism.
Another reason some people think MMR is linked to autism is a study published in 1998 from the United Kingdom. One of the authors claimed that the MMR vaccine could contribute to the development of autism. That study got a lot of attention in the news. Since 1998, 10 out of 13 of the study’s authors have withdrawn their support of the study, and the journal has retracted it.

Where can I learn more about the MMR vaccine?

To learn more about the MMR vaccine or other vaccines, talk to your child’s doctor.

What Is the Current Situation?

In the United States, measles was declared eliminated in 2000 due to high vaccination coverage and effective public health response. That means measles no longer occurs in the United States. However, measles is still common in some parts of Europe, Asia, the Pacific, and Africa. Travelers who have not been vaccinated are at risk of getting the disease and spreading it to their friends and family members who may not be up to date with vaccinations. Because of this risk, all travelers six months and older should be up to date on their vaccinations, regardless of where they are going. Measles is one of the most contagious diseases, and even domestic travelers may be exposed on airplanes or in airports.


As of July 19, 2012, the Ministry of Health in Ukraine has reported 11,760 suspected measles cases in 2012, mostly in the western regions of the country bordering on Hungary, Poland, and Slovakia.
As of June 30, 2012, 1, 765 cases of measles have been reported from Romania in 2012. In 2011 4,015 cases were reported in Romania.
As of June 30, 2012, 655 cases of measles have been reported in France in 2012. In 2011 15,206 cases were reported in France.
As of June 30, 2012, 666 cases of measles have been reported in Spain and 505 cases in Italy in 2012.
As of August 3, 1,450 suspected measles cases (414 confirmed) have been reported in the United Kingdom in 2012, mostly in Liverpool, Knowsley, and Sefton. In 2011 1,083 measles cases were reported in the United Kingdom. Anyone traveling to the United Kingdom who is not protected against measles is at risk of getting infected.

What Is Measles?

Measles is spread by contact with an infected person and through coughing and sneezing. Measles virus can remain active and contagious for up to 2 hours in the air or on surfaces.
People with measles usually have a rash, high fever, cough, runny nose, and red, watery eyes. Some people who become sick with measles also get an ear infection, diarrhea, or a serious lung infection, such as pneumonia. Although severe cases are rare, measles can cause swelling of the brain and even death. Measles can be especially severe in infants and in people who are malnourished or who have weakened immune systems (such as from HIV infection or cancer or from certain drugs or therapies).

How Can Travelers Protect Themselves?

Talk to your doctor to see if you need a measles vaccination before you travel. People who cannot show that they were vaccinated as children and who have never had measles should probably be vaccinated.
The first dose of measles vaccine is routinely recommended at age 12–15 months in the United States. However, children traveling outside the United States are recommended to get the vaccine starting at age 6 months. If your child is aged 6–11 months and will be traveling internationally, talk to a doctor about getting the measles vaccine.
The only vaccines available in the United States are the measles-mumps-rubella (MMR) and the measles-mumps-rubella-varicella (MMRV) vaccines. MMR has been used safely and effectively since the 1970s. A few people experience mild, temporary adverse reactions, such as joint pain, from the vaccine, but serious side effects are extremely rare. There is no link between MMR and autism.

Information for Health Care Providers:

Ensure that travelers are immune to measles before they travel.
  • Children 6–11 months of age who are traveling outside the United States
    • Children in this age group should receive at least 1 dose of MMR.
    • MMR vaccines given before 12 months of age should not be counted as part of the routine series. Children who receive MMR vaccines before age 12 months will need 2 more doses of MMR or MMRV vaccine, the first of which should be administered at 12–15 months of age (12 months if the child remains in a high-risk area) and the second at least 28 days later.
  • Children 12 months or older, adolescents, and adults who are traveling outside the United States
    • International travelers in these age categories who have received 2 doses of MMR or other live measles-containing vaccine are considered immune to measles.
    • International travelers in these age categories are also considered immune to measles if they have had the diagnosis of measles documented by a physician, have laboratory evidence of immunity, or were born before 1957.
    • International travelers in these age categories who cannot be considered immune according to the above criteria should receive 2 doses of measles-containing vaccine (separated by at least 28 days).
If a patient has symptoms of a fever, cough, red eyes, runny nose, and a red, raised rash and has a history of any recent international travel, measles should be considered in diagnosis.
